the flex sensor in ground to the resistor

Can I ask this query about the flex sensor in ground that which the resistor can that be apt to?

the link of the datasheet is below: http://www.sparkfun.com/datasheets/Sensors/Flex/FlexSensor.pdf

I'm appreciate your respond, thanks.

Not sure what your question is? :-?

I’ sorry for that not really clear question.
I mean what the resistor values I can use to the flex sensor in ground.

thanks.

It is not very critical. Basically if you make it the same value as the unflexed resistance you can connect the junction directly to the arduino analogue input port. The data sheet you posted hasn't got that value in it so I would go for 10K. It only affects the offset and span you get from the sensor.

Thank you for your reply. I will give it a try. :)
